The proposed solution is to use robotic irrigation systems in agriculture. These systems consist of special robots equipped with sensors, cameras, and robotic arms. These robots are designed to move around the fields and identify the specific water needs of each crop. They can then deliver water directly to the roots of the plants. The robots can operate on their own by detecting way using camera and CV zone language or can be controlled remotely by farmers. The robots will have four wheels for easy movement and a special arm with a soil moisture sensor at the end. This arm will also have a servo motor to control its movements.

1. The robotic irrigation system works by deploying autonomous robots in the fields. These robots are equipped with sensors and cameras that help them navigate through the crops. They use their sensors to measure the moisture levels in the soil. If a plant requires water, the robot's arm with the soil moisture sensor will detect it and activate the water delivery process. The robot will then move towards the plant, position its arm near the roots, and release water from a water tank. This way, the plants receive the necessary water without wasting any.

Using robotic irrigation systems has several advantages. Firstly, it helps farmers produce more yield because the robots can accurately determine the water requirements of each crop and provide water precisely where it is needed. This ensures that the plants receive the right amount of water for their best growth. Additionally, the system reduces water wastage because water is delivered directly to the roots, minimizing evaporation. It also saves farmers time and effort as they don't have to manually monitor and irrigate each plant.

The robotic irrigation system is different from other solutions because of its efficiency. Unlike traditional irrigation methods where water is applied uniformly to the entire field, the robotic system targets individual plants based on their specific water needs. This ensures optimal water usage and prevents over-irrigation. The use of moisture sensor allows the robot to detect the moisture levels accurately and deliver water only where necessary. 

1. There are a few risks associated with the robotic irrigation system. Technical issues in the robots can occur, which may disrupt the water delivery process or damage the crops. Additionally, if there would be a problem in soil moisture sensor, it may lead to either over irrigation or under irrigation and may reduce crop yield.

1. To implement the robotic irrigation system, the first step would be to design and build the robots with the necessary components such as sensors, cameras, and robotic arms. The robots would be deployed in the fields, and farmers would either let them move automatically or control them remotely. The water tanks would be filled, and the robots would start navigating the fields, identifying crops in need of water, and providing accurate water.

We could compare the crop yield and water usage with other methods to know its evaluation.
